It seems to be only during 3D games. tells me event id 41. Can't find much googling. When i was younger it was always fun to reformat, now it sounds like a hassle. I haven't installed anything new since it started crashing. thanks for reading

The real question is this: did you install anything new BEFORE it started crashing as after it started is meaningless. If you say it's only happening during gameplay then it could be a driver issue or perhaps some heat related problem more than likely.

Look for a program called PC-Check. It is a bootable cd that you can use to diagnose flaky hardware. Only real way to test the PSU is to swap it with a known good one, unless you have an actual PSU tester. Sometimes people buy one local and if that doesn't fix it they take it back.

if its the same PC-check i tested back in the days its pretty bad at finding errors. a lot of false negative.
memory test is weak
CPU test is very weak

Make sure you download the "PassMark Software" version of MemTest 86 (http://www.memtest86.com/download.htm) and not the old Memtest 86+ from memtest.org or elseware.
When using Memtest 86 make sure you choose the UEFI CD/DVD/BD boot option so that it runs version 7.2 and not the older version 4.3 that is included on the same download.
